This mixed methods study examines the creativity of Black girls as they learned to code virtual environments in an afterschool program. The afterschool program, West Philly Tech Camp/Black Girls in Computing was a nine-week program in which students learned to code a virtual chatbot using Python. The program's design was guided by culturally…

When introducing new words in a second language (L2), presenting vocabulary with concurrent gestures might facilitate learners' recollection of new words. Previous research has suggested that this gestural advantage might hold only for gestures that overlap with the semantics of the words. Dual coding theory predicts that learners should learn…

Purpose: This study was designed to test the incremental validity of more expensive vocal development variables relative to less expensive variables for predicting later expressive language in children with autism spectrum disorder (ASD). We devote particular attention to the added value of coding the quality of vocalizations over the quantity of…

This study addresses measurement issues around a standards-based content analysis of mathematics textbooks' coverage of standards for use in large-scale monitoring of standards implementation as proposed in a 2013 report by the National Research Council. An earlier study produced an exhaustive content analysis of textbooks using the 2012 Common…

Steganography is a widely-used technique for digital data hiding. Image steganography is the most popular among all other kinds of steganography. In this article, a novel key-based blind method for RGB image steganography where multiple images can be hidden simultaneously is described. The proposed method is based on Discrete Cosine Transformation…

The purpose of this study was to develop triangulation coding methods for a large-scale action research and evaluation project and to examine how practitioners and policy makers interpreted both convergent and divergent data. We created a color-coded system that evaluated the extent of triangulation across methodologies (qualitative and…

Text classification has allowed researchers to analyze natural language data at a previously impossible scale. However, a text classifier is only as valid as the the annotations on which it was trained. Further, the cost of training a classifier depends on annotators' ability to quickly and accurately apply the coding scheme to each text. Thus,…

In recent years, subject content such as programming and digital literacy has become an integral part of technology education. However, research shows that many programming teachers lack sufficient formal education to teach programming and show disparate educational and professional experiences. This study investigates how three teachers'…

This study was carried out to develop a test to assess algorithmic thinking skills. To this end, the twelve steps suggested by Downing (2006) were adopted. Throughout the test development, 24 middle school sixth-grade students and eight experts in different areas took part as needed in the tasks on the project. The test was given to 252 students…

Modern band programs have spread throughout the United States to create learner-centered and culturally affirming school music experiences for children. The four key concepts of modern band, (1) approximation and scaffolding, (2) decision-making, (3) iconic notation, and (4) culturally sustaining (music education), are congruent with many…

The present study (n = 357) investigates the effects of collaborative note-taking behaviors on learning performance and note quality. To conceptualize collaborative note-taking, the present study introduces the collaborative encoding-storage paradigm, where collaborative writing behaviors are viewed as types of collaborative encoding and the…

The purpose of this research project was to design, deliver, and informally assess the content and methodology of an introductory online course for the educators of Deaf and Hard of Hearing students (N=20) that focused on the block-based coding language, Scratch. Prior work by The Playful Learning Lab examined various STEM resources and their…

The COVID-19 pandemic, an unprecedented global health crisis, has not only significantly impacted public health but has also caused substantial disruptions to conventional education systems. In response to these challenges, our institution has undertaken innovative measures within the realm of education. A pivotal aspect of our response involves…

As digital media consumption becomes an integral part of children's lives, early literacy education must evolve to include foundational contemporary literacy skills. While traditional literacy instruction focuses on reading, writing, and comprehension, young learners also need conceptual knowledge about digital media and literacy before engaging…

Purpose: When we speak, we gesture, and indeed, persons with aphasia gesture more frequently. The reason(s) for this is still being investigated, spurring an increase in the number of studies of gesture in persons with aphasia. As the number of studies increases, so too does the need for a shared set of best practices for gesture research in…
